Method Details

param

AsyncQuery<K,V,R> param(String name,
 Object value)

Sets the named parameter to the specified value

Parameters:

name -

value -

Returns:

skip

AsyncQuery<K,V,R> skip(long skip)

Skips the first specified number of results

Parameters:

skip -

Returns:

limit

AsyncQuery<K,V,R> limit(int limit)

Limits the number of results

Parameters:

limit -

Returns:

find

CompletionStage<AsyncQueryResult<R>> find()

Executes the query

findContinuously

Flow.Publisher<CacheContinuousQueryEvent<K,R>> findContinuously(String query)

Executes the query and returns a Flow.Publisher with the results

Parameters:

query - query String

Returns:

a Flow.Publisher which produces CacheContinuousQueryEvent items.

execute

CompletionStage<Long> execute()

Executes the manipulation statement (UPDATE, REMOVE)

Returns:

the number of entries that were processed

process

default <T>
Flow.Publisher<CacheEntryProcessorResult<K,T>> process(AsyncCacheEntryProcessor<K,V,T> processor)

Type Parameters:

T -

Parameters:

processor - the entry processor task

Returns:

process

<T> Flow.Publisher<CacheEntryProcessorResult<K,T>> process(AsyncCacheEntryProcessor<K,V,T> processor,
 CacheProcessorOptions options)

Type Parameters:

T -

Parameters:

processor - the entry processor task

options -

Returns:

process

default <T>
Flow.Publisher<CacheEntryProcessorResult<K,T>> process(CacheProcessor processor)

Processes entries matched by the query using a named CacheProcessor. The query MUST NOT use projections. If the cache processor returns a non-null value for an entry, it will be returned through the publisher.

Type Parameters:

T -

Parameters:

processor - the entry processor

Returns:

process

<T> Flow.Publisher<CacheEntryProcessorResult<K,T>> process(CacheProcessor processor,
 CacheProcessorOptions options)

Processes entries matched by the query using a named CacheProcessor. The query MUST NOT use projections. If the cache processor returns a non-null value for an entry, it will be returned through the publisher.

Type Parameters:

T -
